Studies not in support

No studies

There are no studies linking foxes to pygmy possum populations.

Evidence linking Burramys parvus to foxes. Systematic review of evidence for an association between Burramys parvus and foxes. Positive studies are in support of the hypothesis that foxes contribute to the decline of Burramys parvus, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance.
